Larger nozzle size ??

Recommended Posts

Is there an easy way to get the ultimaker to print more material/sec via say a bigger nozzle ?

I'm thinking of printer largish objects that don't need amazing accuracy.

Results of small objects have been really good.

If this has been asked before, point me to the answer ... ;)

With a machined 0.8mm nozzle the UM2 can get up to over 16mm^3/sec we found out back in July:


If you want it to go faster than that i belive that the heater and the relatively short melt chamber is limiting the speed, i guess that the UMO probably would be able to go even faster with a enlarged nozzle because of the longer melt chamber and more powerful heater cartridge.

I found a happy compromise at 0.65mm for architectural models and ninjaflex

I just screwed the nozzle into a piece of MDF and put a pin vice with a .65mm drill in my pillar drill (diy drill diy pillar) and it just worked - I drilled from the top.

Might have been beginner's luck ..... oh, I had 5 spare nozzles just in case :) and some spare drills!

Cuts some prints from 12 hours to 4 or less as I do a single pass wall - these are architecture 'makettes' that take up the whole build plate.

I do tend to break up the models though to get the best print orientation and then assemble them - so the glass is used for a really good wall face.

Have a go - it was a 3 minute operation!

Works great for ninjaflex with a slight feeder mod.

PS - this was UM1 - you don't say which one you want to mod.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
